Enlarging
lenses have no built-in helicoid,
because they are usually focused
using a bellows on the enlarger.
Therefore, in order to focus
an enlarging lens when it is
used on a camera, a helical mount
is needed. The Unifoc
12 helical mount makes
this possible. It is extremely
compact with 12mm of displacement

In the shortest setting, the
mechanical length is 17.4mm.
It comes complete with a focus
locking screw.

Enlarging
lenses have no built-in helicoid,
because they are usually focused
using a bellows on the enlarger.
Therefore, in order to focus
an enlarging lens when it is
used on a camera, a focus mount
is needed. The Unifoc
7 mount makes
this possible. It is extremely
compact with 7mm of displacement.

In the shortest setting, the
mechanical length is
20mm.
It comes complete with a focus
locking screw.

Extension
Tubes

Unlike
small and medium format photographic
lenses, enlarging lenses have
no fixed flange-to-image distances.
The distance from the lens to
the camera is different for each
lens with the same imaging dimensions.
Cameras differ also in their
back focal lengths, which means
that the extension length of
the lenses on the image side
must be adapted to the current
image task. This is done with
extension tubes, which can be
combined in different lengths.
They are installed between the
lens and the camera.
